 # FirebaseUI-Android
+
+This library provides the simplest way to bind the Firebase Android SDK to your native Android app.
+Get started now, be running in minutes.
+
+## Using the library in your Android app
+
+To use the FirebaseUI library in our project, we need to do a few things:
+
+1. Add the library to the list of dependencies of our project
+2. Create a class to represent the properties of our objects, as they are stored into the database
+3. Create a custom list adapter to map from Firebase to Android
+
+The FirebaseUI library is most prominent in step 3. But first we have to add it to our project.
+
+### Adding the library to your project (gradle.build or module dependencies dialog)
+
+If your Android app already uses Firebase, you have added a dependency to the Firebase SDK to your dependencies.
+In this step we'll add the FirebaseUI library as another dependency.

+
+You can also add the library dependency directly to your app's gradle.build file:

+
+After the project is synchronized, we're ready to start using Firebase functionality in our app.
